Caption: MODEL RELEASED. Cell culture research. Researcher placing a cell culture sample in a centrifuge. This will be used to spin the sample and separate out the liquid and solid components. The pink liquid is a nutrient medium in which cells can be grown. These cells are being grown for use in experiments to investigate interactions between implantable electronic devices and the human body. Photographed at an INEX facility. INEX is a British microsystems and nanotechnology company that was founded in 2002. One of its research areas is bio-hybrid systems.
